A Defect Petition like DP22001 starts when a person or group formally asks NHTSA to investigate a specific alleged defect. Petitioners submit evidence, NHTSA reviews it within 120 days, and either grants the petition (opening a PE) or denies it with a written explanation in the Federal Register.
Investigators summarized the matter as follows: "The Office of Defects Investigation (ODI) received three petitions on March 17, March 18, and March 29, 2022, which requested a defect investigation into an alleged defect of the "valves" on model year (MY) 2021 Ford Bro..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related FORD files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
The Office of Defects Investigation (ODI) received three petitions on March 17, March 18, and March 29, 2022, which requested a defect investigation into an alleged defect of the "valves" on model year (MY) 2021 Ford Bronco vehicles equipped with the 2.7L Eco-boost engines. The petitioners alleged that MY 2021 Ford Broncos vehicles are experiencing loss of motive power at highway speeds with no-restart due to catastrophic engine failures. On May 27, 2022, ODI opened this Defect Petition to evaluate whether to grant or deny the petition. ODI has identified 26 Vehicle Owners Questionnaires (VOQs) that relate to the alleged defect in the subject vehicles. Based on ODI's review of the applicable materials, including VOQs, NHTSA has decided to grant the petition and open a Preliminary Evaluation (PE22-007) to assess the scope, frequency, and potential safety-related consequences of the alleged defect. Accordingly, this Defect Petition is closed. The ODI complaints cited above can be reviewed at NHTSA.gov under the following ODI numbers: 11448171, 11448461, 11450659, 11450702, 11450737, 11450788, 11450871, 11450879, 11451158, 11451503, 11451957, 11452074, 11452692, 11453669, 11453933, 11454098, 11455294, 11456219, 11456713, 11459262,11460124, 11460125, 11461178, 11463199, 11463296, 11464516.
